So far there is no clear understanding on the etiology and pathogenesis of this neoplasm. To study onthew cell cycle regulation and molecular mechanism would benefit to elucidate the tumorrigenesis of osteosarcoma and establish a new method for treatment.

From May 1979 to Oct 1982, 48 infrahyoid myocutaneous flaps (IHMCF) were used for reconstruction after resection of lingual carcinoma in 44 cases, 4 for carcinoma of retromolar buccal mucosa, 3 each for carcinoma of floor of mouth and parotid gland and 1 each for osteosarcoma of mandible and soft tissue sarcoma of face.

Five μm thickness sections were prepared for staining with haematoxylin and eosin for histopathological assessment and processed for in situ hybridization for assessing the mRNA transcriptions of BMP 2,3,4,5. Sections of osteosarcoma that previously demonstrated consistent expression of BMP 2 mRNA were included in each batch of staining to serve as positive control.

Measurement of bone alkaline phosphatase and relative study with osteosarcoma

The objective of this paper is to explore the value of bone alkaline phosphatase (BALP) for diagnosing osteosarcoma, evaluating the effect of the chemotherapy, judging the prognosis and supervising the relapse and metastasis.

The immunoassay was used to check the BALP of the blood serum that was from 42 primary osteosarcoma patients.

BALP was more sensitive than ALP in diagnosing osteosarcoma (P = 0.015).

It has applied value in the diagnosis of osteosarcoma, reflection of the effect of chemotherapy and forecast the prognosis.

The operative technique was reported in 1980. Two flaps were used simultaneously in 4 cases of lingual carcinoma. When the width of flap was less than 4.5 cm, primary suture of the donor wound could be accomplished. The cutaneous cervical nerve was severed to increase the mobility of the flap. If there was no contraindication, the external and internal jugular vein or part of it including the superior thyroid vein were preserved for better venous return of the flap.

Abstract cases of fibrous dysplasia (FD) in jaws including a McCune-Albright syndrome and an osteosarcoma arising in miaxillary FD were treated by surgical intervention. There were 8 cases performed by subtotal-maxillectomy and 55 cases by plastic trimming procedure. The recurrence rate of plastic trimming procedure was 25. 5%, of which of 20 years old was higher than that of over 21 years old (P< 0.05). The terminology, classification, etiology, diagnosis,treatment, prognosis and malignant degeneration...

The terminology, classification, etiology, diagnosis,treatment, prognosis and malignant degeneration of FD in jaws ware discussed.

The clinicopathologic features and prognosis were discussed with a review of 102 cases of primary osteosarcoma, chon-drosarcoma and fibrosarcoma of jaws. There were more males than females. Their average age ranged from 32 to 39 years. Of these three kinds sarcomas of jaw, the osteosarcoma happened to be the chondrosaroma be the best and the fibrosarcoma be the moderate in prognosis. Their 5 - year survival rates were 40.40 % , 70. 37 % and 52.27 % respectively. Their features of clinicopathology...
